It's not exactly clear why rush shipping was offered in the first place, since all pre-orders were due to be delivered on launch day. Of course, it's not clear why people were willing to pay an extra $12 when it clearly stated the delivery day was the same either way, but hey, pobody's nerfect, right guys?
